IO-Link Validation Error
If an IO-Link device is removed in COM mode and the validation is parameterized, or a valida-
tion error is detected, e.g., due to an incorrect vendor ID or device ID, the following diagnostic
bits can be set in the IO-Link master status data:
This includes:
•
MI-FMA
: Module information
—
force mode active
•
MI-VAL
: Module information
—
IO-Link validation error
•
MI-SCB
: Module information
—
actuator short circuit, channel B
•
MI-SCA
: Module information
—
actuator short circuit, channel A
•
MI-SCS
: Module information
—
sensor short circuit
•
MI-LVA
: Module information
—
low-voltage auxiliary power supply
•
MI-LVS
: Module information
—
low-voltage system/sensor power supply
•
VAL-X1A ... VAL-X8A
: IO-Link master validation error, channel A (pin 4, C/Q) of connections X1 to X8
IO-Link device diagnosis
The diagnosis of IO-Link devices contains errors, a warning, or a notification.
IO-Link Device Error
In the event that a device sends a fault diagnosis to the master, the following diagnostic bits can
be set in the IO-Link master status data:
This includes:
•
IOL-DN
: Module information
—
IO-Link device notification
•
IOL-DW
: Module information
—
IO-Link device warning
•
IOL-DE
: Module information
—
IO-Link device fault
•

X1 to X8
•
DW-X1A ... DW-X8A
: IO-Link device warning message, channel A (pin 4, C/Q) of connec-
tions X1 to X8
•
DN -X1A ... DN -X8A
: IO-Link device notification, channel A (pin 4, C/Q) of connections X1
to X8
•
VAL-X1A ... VAL-X8A
